PREFACE 



This manual is primarily written for agricultural 
students attending- Agricultural Colleg-es. The prin- 
cipal thing kept in mind in selecting, compiling and 
arrang-ing- the exercises was to stress only those 
thing's which are necessary to a thoroug-h understand- 
ing- of farm machinery, its selection, care and opera- 
tion. 

Three types of exercises will be found : those that 
deal with the examination of the machine from an 
investig"ational standpoint ; those that call for the 
taking- apart and reassembling-, and those that test 
machines. 

The first named exercises are to get the student 
familiar with the different parts of the machine, the 
principal differences in the various makes of the same 
tjrpe of machine and the function of each part. For 
these exercises there are questions asked, the answer 
to which the student must determine and jot down 
aside of the question. Blank spaces are left for these 
notations, or, if no blank space is left, the part of 
the question not applying to the machine can be 
crossed out. So when the machine is finally com- 
pleted, there is a complete statement of the machine. 
Suificient machines of the same kind should be 
gone over to fill out all the report sheets for that 
machine. After the report blanks for one kind of 
machine, such as walking plows or mowers, etc., are 
filled out, then the student should present himself to 
the instructor for a quiz on that machine. A grade 
will then be given. 

In the case of assembling and testing exercises, 
the student does the exercise as per instructions in 
the manual and additional instructions from the in- 



Faem Machinery Laboeatoby 



structor. All results should be carefully tabulated 
in manual. 

Each student will need a manual and a pocket 
tape. As soon as getting the manual the student 
should write his name on it ink, thus insuring its 
return in case of loss. Not more than three students 
should work together if all are to get the maximum 
benefit of the course. 

In using the machinery and apparatus in the lab- 
oratory, take care of it as well as you would if it 
were your own. Keep in mind that, while the 
machinery is loaned to us and the apparatus belongs 
to the State, yet there are many other students com- 
ing after you and they too wish to have good ma- 
chinery and apparatus to use. 

Do not rush through your laboratory work or do 
not loaf. Work right along making each moment 
count for the most. Get all you can out of the labor- 
atory work. Do not run to the instructor with every 
little question, but try to rely upon yourself. Eemem- 
ber that the laboratory work is built on the assump- 
tion that you have the class room work in good 
shape ; if you fail there, you are lost here.

GRAIN DRILL CALIBRATION 



Instructions. 



EXEBCISE No. 37. 



Calibrate a grain drill with two different kinds of 
seed ; make two tests with each seed, sowing differ- 
ent amounts each time. 

Get some clean seed from instructor who will 
tell you the amounts to sow per acre. Set the drill 
to sow one of the amounts. Measure width of drill 
and circumference of wheels in feet. Determine the 
number of revolutions that the wheel must go in 
order to sow an acre. Place sufficient seed in seed 
box to sow one-fourth of an acre. Turn wheel until 
all the seed are gone, keeping count of the number 
of revolutions. Compute the per cent drill is inac- 
curate.
